To all 'Lc/wm, 'it may coi/:cern

lie it known that l, Vio'roiz Eimits'r Joven. a subject of the King of Great .lritaiin residing :it lioinlen, England, haveinveiited new and useful Improvements in and l-clating to Mixing Valves or Cocks. of which the following is a spccilieation.

This invention has for its object improvemonts in and relating to mixing .alves or cocks whereby water or other fluids at ditl'crent temperatures are mixed in the mirel and delivered therefrom at 'the ,lesireil teni.- perature, the relati' A proportion of water or lluid at the various temperatures adi'nlted to the vulie. heilig mriable b v adjusting the position ol' the valve.

The invention consists in an improved and simple construction of valve ol' the kind above described whereby the water or iuids at (iill'erent `texoi'ieratu-i'es are thorou mixed in theI vali e before delivery therefrom at any desired temperature2 for instance to a bath or other receptacle, und wherein a perfectly luid tight Lioint is made iu the valve when in the closed position by inox-ins of a conical or like resilient block or piece on the plug which seats against i conical valve` seat formed at a suitable point or place in the p= .ge-way for fluid `tlirough the mixing valve.

The valve according to this invention may ot' course be employed for mixing different kinds of liquids or lluids.

According to this invention the mixing valve is so constructed that the fluids enter the `valve casing and pass upwardly through the plug and valve casing to the upper portion of the latter, from `which upper portion the delivery or discharge outlet takes oli", and by being compelled to take a more or less tortuous and upward course through the valve become thoroughly mixed therein he fore-delivery to the bath or other vessel or receptacle. The valve is provided with a hollow plug or piston which is adapted to be moved up and down in a vertical cylin drical casing. The valve plug or piston is j guided in its movements by means of a stud in the interior of the valve casing engaging with a groove in the exterior of the plug and it may have a straight up-and-down motion; in Whichcase .the groove in the plug would be a. straight vertical groove or it may have a combined up-anddown and rotary movement in which oase the groove in the eiently greater than the diameter of they valve spindle to allow of the liuid passing upwardly.around the spindle when the valve is open, and a block ot' suitable resilient niateriaL-such as dei'rnatin,-surroundingthe spindle beneath the valve seat and being adapted when the plug is in its uppermost position to scat itself against the valve seat and close the valve against the passage of (luid. .X plurality of fluid supply pipes is connected to inlet ports in the valve casing and the valve plug or piston is provided with a port adapted to be placed in registration with any one or any adjacent two of such inlet ports or to be moved out oi' registration with any such ports as when the valve is closed. In the forni of construction ot' the valve in which the valve plug or piston has a straight up and down movement only'a spiral springr or the like is placed beneath the valve plug and is adapted to normally hold the valve in its closed' position.

lVith va lves constructed according to this invention it is not essential that the valve pistons or plugs tit the valve casings tightly. The pistons or plugs in fact are arranged to work freely in the cylindrical casings and with vsuch an arrangement it will be found that the. plugs will not seize when they expand due to the passage of hot liquids through them.

The 'invention is illustrated the acconipanying drawings, in which Figure l is asectional elevation of a inining valve constructed according to this invention; F ig. 2 is a sectional plan taken on the line H-I, Fig. l; Fig. 3 is a plan oi the mixing valve shown in Figs. l. and 2, this view also showing portions ot the uic inlet pipes; Figs. 4 and 5 are respectively an elevati-on and a vplan of the valve plug of Figs; l, 2 and 3 removed from its casing; Fig. G is sectional elevation of another `form of construction. the mixing valve may take; Fig. 7 is a sectional elevation of ps rt of the valve ping and casing of .on the 2t lof the valvecasin iine vit-vn, Fig. 6, and Fig. s is .i pian i 12 ina, ort through the wall oft #valve p ug 2 adapted to be placed in the regfio matin,-surrounding the' spindle 3. The

' block 13 is formed conically at itsuipper end i 18 is a spindle 3 vidin i valve is closed. gasket 22 is placed betr and the u wof the valve plug of Fig. 6.

Referring to the drawings, the valve shown in Figs. 1 to 5 inclusive is especially intended for use with baths but of course 1t is not limited to such use the valve shown in Figs. 6 to 8 inclusive eing suitable for lavatory basins. In Figs.4 1 to 5, inclusive, 1 is the outereasing. of the valve and 2*.the valve plunger or plug, which is provided -with av spindlez3 and operatin handle 4. 5 is the discharge or delivery out et from the valve casing 1, and 6, 7 and 8 are respectively inlet ports for cold, hot and boiling water, 9, 10 and 11 being the supplly pipes.

` e hollow istration with any one or an adjacent two of the ports 6, 7, 8. 13 is a b ook of suitable resilient'materiaL-such for instance as derand is kept; in place by a collar 14 suitably Secured, as by a screw, on the spindle 3. 15,

15 are orts formed in the upper wall or end liollow plug 2. The upper end of the i`s closed by a screw cap 16, 1 7 being a ae ting gland around the spindle d. oiizontal partitionpiece which is adapted to be screwed into position by any suitable ineans,as shown by a ky'or like tool engaging in the' holes 19, 19. hole 2O l'h the center of the partisiiilieiently greater than 'the diameter of the as to leave a passage for fluid around said spindle. Thelower portion of the hole 20 is formed conicall'y thereby roa `conical valve seat 21 against w ich the b oel: 13 is adapted to seat when the A suitable packing ring or veen the screw cap 16 per edge of the valve easing l, anda pac 1n riiilg 23 is also provided between the unersi e of the piece 18 and the shoulder 24 in the interior of the valve casing. In the valve according to Figs. 1 to 5 the valve plunger 2 has a rotary as well as an up-and-down movement and is guided in' its movementby a pin 26 (see Fig. 2) fixed in the interior ofthe' valve easing 1 engaging in a groove 27 (see Figs. 2 and 4) in the exterior of the hollow lunger 2. This ,ve may be 'cut helica ly throughout its or may bc partly helical and partly horlkonta-l as shown on the drawings.

,It will be seen that' by operating the .handle 4 the valve plug 2 may be rotated, and the port 12 may be put in registration with one only of the ports, 7, 8 or -with ports 6 and 7 or ports 7 and 8. rlhe horizontal portion of the groove 27 is provided so that the port 12 need not -be oi a much greater vertical length I than the vertical ength' ofthe ports 6, 7, 8, and when the handle is operated the plug will not more vertically up or down w iile the pin 26 1s in the horizontal portionA of the groove 27, but only when it is in the helical portion ofthe groove. When the pin 2G is in the helical portion of the groove 27 the operation of the handlel 4; in one direction will cause the valve plug 2 to rise while operation of said handle in the other direction will cause the valve plug to -inove downwardly. When the valve plug is in its uppermost osition the block 13 will seat against the vii ve seat 21 and close the valve, the port 12 at the same time beingout of registration with the ports', 7, 8.

When the port 12 is in registration with one or two of the inlet ports 6, 7; 8 the fluid from said port or ports will p iiss into the hollow interior of the valve plug und u i# whence it will e discharged by the outlet 5. If the port 12 is in .registration with two ports, say'6.and 7, the fluid delivered by the supply pipes will be thoroughly mixed during its upward and somewhat tortuous passage through the plu and valve casing before it is discharge from the valve.

ln connectionl with the valve constructed according to Figs. 1 to 5 an index showing the temperature of the water delivered by the valve in 'its various positions may be provided on the cap 16, a pointer` 37 bein provided on the handle 4 to coperate with the said index.

Referring to Figs. 6, 7 and 8, the 'com struction here shown is such that the valve plug has a straight up and down motion f only, the .slot 28 being in this case cut vertically in the exterior of the plug 2. The port 29 is in this case made narrow and elongated horizontally while the ports 30, 31l and 32 are arranged at different levels or heights in the casing. In thiseonstruction of valve a spring 33 is provided which, by acting against the partition 34r in the valve plug, tends to hold the plug 2in its up ermost position closing the valve 38. hev valve spindle 354is provided with a knob handle Biliinstcad of with the lever handle 4.- shown in Figs. l and 3. The valve is opened to admit fluid to the lavatory basin or other desired receptacle by pressing down the knob 36, and the operation of the valve will be clearly understood without any further detailed `description.
